STOMACH=PUMFL SPECIFICATION forming part of Letters Patent No. 686,281dated November 12, 1901. Application filed May 28, 1901. Serial No.62,223. (Nomorleh) To aZZ whom it may concern.-

Be it known that I, WAITE GERRY, a citizen of the United States,residing at Ventura, in the county of Ventura and State of Galifornia,have invented certain new and useful Improvements in Stomach-Pumps, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to new and useful improvements in stomach-pumps 5and its primary object is to provide an attachment whereby the tube ofthe pump may be readily swallowed without either buckling or slippingoutward during such action. v

With these and other objects in view the invention consists in providinga knob of suitable material, such as soft rubber, which is connected tothe end of the pump-tube by means of a cord formed with or secured to.

both the tube and knob.

The invention also consists in the novel construction and combination ofparts herein after more fully described and claimed, and illustrated inthe accompanying drawings, showing the preferred form of myinvention,and in whicl1-- Figure 1 shows a pump with the attachment formedthereto. Fig. 2 is a detail view of the attachment and showing insection its point of connection with the tube. Fig. 3 is a detail viewof a modified form of attachment.

It has been found in the use of stomachpumps that the tube when insertedinto the throat has a tendency to buckle up during the act ofswallowing. Moreover, the muscles of the throat fail to grasp the tubefirmly, and as a result the same will slip outward under a very slightpull thereon. To overcome these objections, I provide an attachmentwhich may be formed with the tubes of stomach-pumps or may be connectedto pumps now in use. This attachment comprises a small knob 1,preferably substantially pear-shaped and formed of any suit ablematerial, such as rubber. A flexible stem 2 connects the small end ofthe knob with the end 8 of the pump 4, and this stem is preferablyformed integral with the tube and knob.

In Fig. 3 I have shown a modified form of attachment which can bedetachably secured to a pump-tube. This comprises the knob 1 and astrong cord 5, which is passed through small apertures 6 and 7 in theknob and tube, respectively, and tied.

In use the knob 1 is placed in the throat and is firmly clasped andnearly surrounded by the muscles of the throat during the act ofswallowing. The knob is drawn downward by the muscles and pulls the tubeafter it, thereby preventing buckling of the tube. Moreover, as thethroat-muscles extend over the knob it is prevented from accidentallyslipping outward;

In the foregoing description I have shown the preferred forms of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore re serve the rightto make such changes as fairly fall within the scope of my invention.

I claim 1. In a stomach-pump, the combination with a tube; of a knobhaving a reduced portion, and a cord secured to said reduced portion andto the end of the tube.

2. In a stomach-pump, the combination with a tube; of a solid knob, anda cord connecting the knob to the end of the tube, said cord passingthrough apertures in the knob and in the closed end of the tube.

In testimony whereof I aifix my signature in presence of two witnesses.

WAITE GERRY.
